Management of Heat Underground. Case Study of Deeps
Radiocarbon dating and the upper forest line (UFL) was most probably lower than present-day. Between 11,660 - 4280 cal yr BP, a marked decrease of páramo vegetation occurred, accompanied by an expansion of probably played an important role in controlling changes of the upper forest limit during the late Holocene.

(Adatte et al., 1991; Rentzel, 1990). The dating of the se-quence is based on techno-typological elements, variation in the mineralogy, and a few charcoal radiocarbon ages. The lat-ter, originating from two individual archaeological find lay-ers, are at the upper dating limit and suggest a minimum age of 40ka for the lower part of the site.

In an arctic climate this is not possible. Also the radiocarbon dates cannot be correct. Because during the time, in which the mammoth is supposed to have lived there, it could not have lived there at all. The mammoth calf Dima has lived in the year 2370 B.C.E. near the upper Kolyma River in northeastern Siberia. That is 4,368 years ago (in 1998).

Radiocarbon dating - ReadkonG
Dendrochronology or tree-ring dating is the scientific method of dating based on the analysis of patterns of tree-rings. Dendrochronology can date the time at which tree rings were formed, in many types of wood, to the exact calendar year. This has three main areas of application: paleoecology, where it is used to determine certain aspects of past ecologies (most prominently climate

over millennia, and to determine the age of upper surface peats. The northern part of Pur-Taz interfluvial region (Fig. 1) was chosen for a study of the history of the vegetation because of its proximity to the northern limits of birch, larch and spruce trees (Arealy drrev'ev i kustarnikov SSSR 1977).

Radiocarbon Dating. The most commonly used radiometric dating method is radiocarbon dating, carbon-14 or C-14 dating, used to date organic materials such as charcoal, wood, bone and antler, or marine and fresh-water shell, or any tissue that was once alive.
Lena River delta formation during the Holocene
The lower forest subzone on the west -facing slopes of the southern Barguzin Range (456-600 m a.s.l.) comprises larch forests and pine scrubs (Pinus pumila) (Fig. 2A). Scots pine prevails in the subzone of mixed taiga forest (600 -850 m). In the upper forest subzone (850 and 1150 m) the forest c ommunities are formed by Siberian pine

Methodology. Chronostratigraphy relies heavily upon isotope geology and geochronology to derive hard dating of known and well defined rock units which contain the specific fossil assemblages defined by the stratigraphic system. However it is practically very difficult to isotopically date most fossils and sedimentary rocks directly, and thus inferences must be made in order to arrive at an age
Gamma spectrometry for chronology of recent sediments
ice limits are known for only four localities in southern Nor-way, and the earliest limit is based on a single record. Dating is problematic because the time period of interest is beyond the applicability of radiocarbon dating. Even in younger sediments only intervals between glacier advances contain enough organic material to be used for this

lower limit of Podocarpus was certainly below 1,100 m and the actual temperature depression > 4.5°C . . .
